Studies on the chemical constituents of the marine sponge Cina-chyrella australiansis from the South China Sea / 中国海洋药物

Five compounds were isolated from the ethyl acetate extract of the marine sponge Cin-achyrella australiansis collected from the South China Sea. Their structures were identified by IR,1 H-NMR,13C-NMR,MS as the follows : 24-ethyl-cholest-4-en-3-one(Ⅰ), cholesterol (Ⅱ), benzene- ac-etamide(Ⅲ), p-hydroxyphenylacetamide(Ⅳ), indole-3-acetamide(Ⅴ).

Research advances of Glycosphingolipids / 中国海洋药物

Marine Glycosphingolipids(GSLs) compounds mainly come from marine ogranisms of marine sponge and starfish. The advances of study on GSLs compounds in recent two decades were reviewed. The relationship between chemical structure and biological functions of GSLs compounds was also described.
